CLOSUBE FOB BEARINGS.

.Application led latch '10,

This invention is designed to provide simple, inexpensive and efficientmeans for closing a bearing to exclude foreign matter therefrom andretain a lubricant therein,

6 and while of general utility'is especially designed for use in the hubassembly described and claimed in my co-pendin appllcation, which hasmatured into atent v1,437,333.

My improvements are'characterized by a felt or similar washer held inthe channel of a circular shelll formed of two metal rings of angularcross section having circular' parts of unequal width and diameter larranged in laminated relation with trans.-

`verse webs suitably spaced to p vide the sides of a channel-for thewasher, t composite ring thus formed having a la inated flangeprojecting `laterally from said chan- The improvements are furthercharacterized by their adaptability for ready application to and incombination with hubs and spindles to effect the enclosure of theantifriction bearings disposed between them.

In the drawings, Fig. 1 is a side view of a device embodying myinvention; F'

is a sectional view taken on a diameter thereof, and Fig.

3 view illustrating the application of the def vice to a hub and spindleto effect the closure of the spacebetween them.

The invention, in the form '-thereofjllustrated, comprises the pressedmetal ring 1 having the cylindrical periphery 1 with the web 1"extending inward y from an edge thereof and the pressed metal ring2fhaving the .cylindrical periphery 2 (narrower than the periphery 1')with the web 2]extend- 40 ing inwardly from an edge. thereof, thepart 1. having'an inner diameter substantially' equal to the outerdiameter of the part 2 so that such parts can be fixed together inlaminated relation and form a cylindrical flange extending laterallyfrom the channel formed by or between the parts 1 and 2,`whose inneredges have equal diameters as shown.

A ring or washer 3, of suitable fibrous niaterial such as felt, is heldin the shell thus formed, between tbe parts 1 and 2, with Vits peripherybearing against the part 1,

the inner diameter of this ring being smaller than that of the parts 1and 2 so that, it

extends inwardly beyond them.

The closure thus formed. is combined, as

illustrated in Fig. 3. l and a spindle v5 to effect the closure of thespace between them; to exclude grit, and other foreign matter and toobtain a lubricant. v r

the inwardly projecting flange 1- the cup 6, and on the section 5 innerend abutting against the cylindrical shoulder 5" at the inner end of thespindle, the conical rollers 8 being the bearin therein, with the partgag by against 'the' making contact with the peri hery of the part 5'.which sembling the structure.

comprising a plurality of L- haped cross section; a metal shellcontaining a circularchannel and having a circular laminated flangeextending therefrom,

10 la composite ring of substantially uniform diameter throughout itswidth, formed of ing cross-sections containing' reentrant angles, saidparts-having concentric surfaces engaged in frictional relation andanges extending therefrom providing a channel for a fibrous ringdisposed in and extending beyond said channel.-

In testimony whereof .I have hereunto set my name this 6th day of March,1922,
